Setup is correct
I have a 323 with the Pryde bag setup. The forward lead goes ties to the slot in the bag closest to the mast. this is threaded through a stainless steel ring and tied off to a second stainless ring. A second line is tied to the second slot in the bag, threaded through the tied off ring on the first line and secured to the last slot in the bag. The final linw is attached to the loose ring, threaded through the spreader, and tied off to an attachment point on the mast above the spreaders. If you contact customer service at BeneteauUSA.com, they may be able to send you an illustration.There should be a fairly good illustration of this in your owners manual.I have replaced the uuper attachment on the with harken blocks and led the lines to cleats on the back of the mast so that I can adjust the lazy jack lines, or drop the bag completely.Yes, the lines wear on the eyelets in the spreaders. I just had one break last week. I'm getting ready to go up the mast to replace both lines today or tomorrow. The original 6mm line I had was too short and I had replaced it with 3mm. I am now going back to 6mm line.I have never been crazy about the setup, but it does work when we're short handed on the boat. It certainly beats in-mast furling in my opinion.
